Configuring STP on the Switch
Summit 300-48 Switch Software User Guide 149
3 Enable STP for one or more STP domains using the following command:
enable stpd {<stpd_name>}
NOTE
All VLANs belong to the default STPD (s0). If you do not want to run STP on a VLAN, you must add the
VLAN to a STPD that is disabled.
Once you have created the STPD, you can optionally configure STP parameters for the STPD.
CAUTION
You should not configure any STP parameters unless you have considerable knowledge and experience
with STP. The default STP parameters are adequate for most networks.
The following parameters can be configured on each STPD:
• Hello time
• Forward delay
• Max age
• Bridge priority
The following parameters can be configured on each port:
• Path cost
• Port priority
NOTE
The device supports the RFC 1493 Bridge MIB. Parameters of only the s0 default STPD are accessible
through this MIB.
Table 53 shows the commands used to configure STP.
Table 53: STP Configuration Commands
Command Description
config stpd <stpd_name> add vlan <name> Adds a VLAN to the STPD.
config stpd <stpd_name> forwarddelay
<value> Specifies the time (in seconds) that the ports in
this STPD spend in the listening and learning
states when the switch is the Root Bridge.
The range is 4 through 30. The default setting is
15 seconds.
config stpd <stpd_name> hellotime <value> Specifies the time delay (in seconds) between
the transmission of BPDUs from this STPD when
it is the Root Bridge.
The range is 1 through 10. The default setting is
2 seconds.
